The aim of this study was to identify a situation of stratospheric to tropospheric air mass transport (STT), and then attempt to answer the question whether beryllium ( 7 Be) can be a good marker of stratospheric ozone (O3) origin in the surface boundary layer of the atmosphere (SL) and its role in the tropospheric ozone budget. The sets of data covering the yearly period are examined such as: the daily activity concentration of 7 Be and lead ( 210 Pb), the hourly concentration of ground-level ozone O3 and the meteorological parameters measured in SL in a meteorological station located in the town of Raciborz in southern Poland. The data obtained had undergone statistical and Fourier analysis. The data obtained had undergone Fourier analysis in order to eliminate the periodicity associated with, inter alia, the annual variability of solar radiation incoming to the Earth’s surface. Then, based on statistical analysis potential days in which very likely was the occurrence of the so-called phenomenon “stratospheric intrusion” (SI) were identified. The selected periods were then analysed in terms of synoptic assessment of the impact of meteorological conditions on levels of 7 Be and O3.
